The present invention relates to a self propelled kit applicable to agricultural buckraking machines or silo-bag, the type which is utilized for grain storage in fields, and which is constituted by a reception hopper, a filling tunnel, a worm gear or load screw for the filling of the connected bag.
Grain buckraking machines that are currently known are those which carry out the grain storage depending on the use of a tractor or a similar vehicle. This vehicle is connected to the machine at the moment of working and through a transmission or cardan joint, which receives the tractor command, gives movement to the worm gear through the force bar, and control of the advance direction though its steering wheel and wheels.
It should be clear that it is not possible to carry out grain silages without a tractor or the like, since neither the worm gear would be moved nor it would allow the buckraking machine to advance in the desired direction. The great disadvantage which arises with the need to use a tractor is that it cannot be used for other important tasks such as silage, generating delays as a consequence. If we imagine a field where people are silaging in four different areas, firstly we would need four tractors to carry out grain storage simultaneously and those tractors would be unavailable to carry out other tasks.
While it is working, the grain will get into the upper reception hopper of the buckrake from the self-unloading part in order to be taken by the grain load's worm gear that will make the grain enter into the bag. As a consequence, the bag will be gradually filled with grains and, because of the pressure on a deflection torque that is in the buckrake, a drive forward will be produced. In that way, the whole equipment will move forward, and its direction will be controlled by the tractor's direction. It is important to think of energy and fuel that it is going to be consumed in moving the tractor and the activation of the worm gear.
The present invention comprises a kit which can be easily adapted to any buckrake in the market, and allows people to work without using the tractor, leaving it for other tasks.
The kit of the present invention is applicable to buckraking machine or silo-bag, wherein the buckraking machine includes a reception hopper, a filling tunnel, a worm gear or load screw for the fitted of the bag storage, and a work spear. The self-propelled kit comprises:
a movable base having at least one wheel;
an independent engine mounted on the movable base, wherein the independent engine activates the worm gear or load screw;
a clutch mechanism coupled to the independent engine;
a coupling fuse coupled to the clutch mechanism;
a speed reducer coupled to the coupling fuse; and
a short cardan joint coupled to the speed reducer at one end and to the hopper in the other end.
Although buckrake solutions that make no use of a tractor are known, they achieve the grain load by simple gravity. Those machines do not obtain successful grain storage and result totally discarded for grains with low specific gravity. Therefore, the result is a low percentage of bag storage and wastement of the bag's volume.
The present set of elements guarantee a total and effective storage of bags, permits its use with any dry grain, replaces the use of the tractor, attaining the worm gear's movement and self-propulsion through a 13 HP engine, a hydraulic automatic clutch, a coupling fuse, a speed reducer gear, a short cardan joint. Likewise, a much softer, uniform and without vibrations bag storage is obtained since the transmission cardan joint was shortened.
As regards the engine to be used, it can be a gasoline engine, a diesel, a CNG (compressed natural gas) engine or an electric one. The latter has important limitations because in places where bag storage takes place, generally there is no electric current. Preferably, the clutch should be hydraulic automatic but it can be replaced by a mechanic one.
The directional wheel of the buckraking machine will be constituted by a wheel made of a disc-shaped central sheet with two cylindrical bodies as wheels by each side. The previously mentioned disc will stick in the ground and it will allow the machine to be directed in all types of land. The cylindrical bodies will include wings for a better adherence to the ground.
The previously mentioned characteristics will allow the buckrake to storage bags in all kinds of lands, like mud, high pasture, even with water on the ground and at the same time the movement from one field to another by wagon.
In order to make the object of the present invention more intelligible, it has been illustrated with schematic Figures, in their preferred embodiment thereof, which assume a demonstrative example in them:
